Use GUI, CLI or API to Connect an App in a VPC to app in IKS

Purpose

The purpose of this scenario is to connect an App in VPC to an IKS deployemnt on IBM Public cloud. It demonstrates establishing a VPN connectivity between VPC resources and Kubernetes workloads on IKS over a secure vpn tunnel. It is based on concept of Setting up VPN connectivity to IKS

There are two goals for this scenario:

1. To prove that connectivity can be established between VPC and IKS
2. To build the enablement material to show how to establish the connection between VPC and IKS

Prerequisites

The common prerequisite to starting the VPC specific steps is to setup the IKS cluster and deploy helm onto it. Details for both the tasks can be found in the following IBM cloud documentations.

• An IBM Kubernetes Service cluster deployment.
• Helm deployment on IKS: Setting up Helm in IBM Cloud Kubernetes Service

Deploying the Scenario

• Deploy using the CLI
• Deploy using the UI
• Deploy using the API
